File:Saturn, its rings, and a few of its moons.jpg
Atmosphere: 96.3% hydrogen and 3.25% helium
Tempreture: -175 degrees C
Mass: 5.6846 × 10 kg
Density: 0.687 g/cm³ Diameter: 74,900 miles (120,540 kilometers)
Distance from Sun: 840,440,000 miles (1,352,550,000 kilometers) ~ 941,070,000 miles (1,514,500,000 kilometers)
Days of orbit: 10,759 Earth day or 29 1/2 of Earth year.
Intro: Saturn is the second largest planet. Saturn has seven layers of ring around it. The rings consist of numerous narrow ringlets, which are made up of ice particles and rocks that being pulled by Saturn's big gravity. The planet can be seen from Earth with the unaided eye, but its rings cannot. Saturn was the farthest planet from Earth that the ancient astronomers knew about. They named it for the Roman god of agriculture.
What you might need: -A hot-air balloom, because Saturn's atmosphere is the best place in the whole solar system to fly them.
-A pair of dance shoes might be good, because there actually no night on Saturn, even if its night, the ring reflect sun light from the Sun. -Also calendar will be needed, because 1 Saturn year is 10,759 Earth day, so you might need a calender to keep you up to date.
-Your can also bring your water skis set, because Saturn's planet, Titan, is a liquid world, rivers, lake and stormy weather make a good place to practice water skis. (But the liquid isn't liquid water, its liquid mathena.
-You might need some extra clothes there, because Saturn's atmosphere tempreture is -175 degree C, and season may stay the same for a long time without changing.
-You also need some summer clothes, because under Saturn atmosphere, its petty hot, some scientist had spotted that Saturn gives off more heat than it receive from Sun.
Interesting placesSaturn's Ring
The rings of Saturn surround the planet at its equator. They do not touch Saturn. As Saturn orbits the sun, the rings always tilt at the same angle as the equator.

The seven rings of Saturn consist of thousands of narrow ringlets. The ringlets are made up of billions of pieces of ice. These pieces range from ice particles that are the size of dust to chunks of ice that measure more than 10 feet (3 meters) in diameter.
Saturn's major rings are extremely wide. The outermost ring, for example, may measure as much as 180,000 miles (300,000 kilometers) across. However, the rings of Saturn are so thin that they cannot be seen when they are in direct line with Earth. They vary in thickness from about 660 to 9,800 feet (200 to 3,000 meters). A space separates the rings from one another. Each of these gaps is about 2,000 miles (3,200 kilometers) or more in width. However, some of the gaps between the major rings contain ringlets.
Saturn's rings were discovered in the early 1600's by the Italian astronomer Galileo. Galileo could not see the rings clearly with his small telescope, and thought they were large satellites. In 1656, after using a more powerful telescope, Christiaan Huygens, a Dutch astronomer, described a "thin, flat" ring around Saturn. Huygens thought the ring was a solid sheet of some material. In 1675, Giovanni Domenico Cassini, an Italian-born French astronomer, announced the discovery of two separate rings made up of swarms of satellites. Later observations of Saturn resulted in the discovery of more rings. The ringlets were discovered in 1980.
